Localized bases for finite dimensional homogenization approximations with non-separated scales and high-contrast [PDF]

open access: yes, 2010
We construct finite-dimensional approximations of solution spaces of divergence form operators with $L^\infty$-coefficients. Our method does not rely on concepts of ergodicity or scale-separation, but on the property that the solution space of these ...

New applications of the fractional derivative to extract abundant soliton solutions of the fractional order PDEs in mathematics physics

open access: yesPartial Differential Equations in Applied Mathematics
The motive of this research work is to unravel the mysteries of nature through fractional-order partial differential equations (PDEs). Here, we focus on two important fractional order nonlinear PDEs, namely the fractional order (4+1)-dimensional Fokas ...

Periodic motions galore: How to modify nonlinear evolution equations so that they feature a lot of periodic solutions

open access: yes, 2002
A simple trick is illustrated, whereby nonlinear evolution equations can be modified so that they feature a lot - or, in some cases, only -- periodic solutions.

Rigorous a-posteriori analysis using numerical eigenvalue bounds in a surface growth model

open access: yes, 2017
In order to prove numerically the global existence and uniqueness of smooth solutions of a fourth order, nonlinear PDE, we derive rigorous a-posteriori upper bounds on the supremum of the numerical range of the linearized operator. These bounds also have

Spatial smoothness of the stationary solutions of the 3D Navier--Stokes equations

open access: yes, 2006
We consider stationary solutions of the three dimensional Navier--Stokes equations (NS3D) with periodic boundary conditions and driven by an external force which might have a deterministic and a random part.
